Botrytis Control
[0101]Botrytis is an opportunistic fungal plant pathogen that is very difficult to control on fresh market tomatoes under field conditions due to its ability to colonize both foliage and stems of the plant canopy, as well as of the developing fruit. In addition, Botrytis can manifest itself as a basal stem lesion at the soil level and girdle plants, thereby killing the plant outright and reducing yields accordingly. These characteristic of Botrytis make control with sprayable fungicides very difficult and sometimes even more difficult to evaluate among several under experimental conditions. Nevertheless, this experiment established that application of hop acids and their derivatives can be used to treat or prevent Botrytis cinerea infestation of susceptible fresh market tomato planting.
[0102]Susceptible tomato plants were overhead misted to encourage disease establishment. These studies were conducted in San Luis Obispo, Calif. where normal coastal conditions also en...

Lepidoptera Control
[0111]This study was done in summer of 2005 at the research farm of Pacific Ag Research in San Luis Obispo, Calif. to determine the efficacy of BetaCide at a rate of 10% for control of Lepidoptera pests on fresh tomatoes. Avaunt and Success were used as positive controls. Results with BetaCide, Avaunt, and Success were compared with those in 2 untreated control plots. The pest pressure was moderate. Insecticides were applied in four applications every 7-15 days. BetaCide was applied at 10% volume per volume in water (v / v); Avaunt was applied at 167 g / ha; Success was applied at 208 ml / ha. Treatment applications were performed using a CO2 backpack sprayer. The spray boom incorporated five D4 nozzles with #25 spinners and was operated at a pressure of 40-50 psi. Treatments were applied at a dilution of 65-85 GPA. The boom size was adjusted according to the growth stage of the plant to ensure a thorough foliar coverage. The diagram in FIG. 6 illustrates the boom used....

Lepidoptera Control on Broccoli
[0115]BetaCide was evaluated for the control of several Lepidoptera pest species on broccoli in the summer of 2005 in Santa Maria Calif. During this season, larval populations were sporadic. Therefore, foliar evaluations of larval feeding following the application period was used to examine whether Betacide was effective in controlling Lepidoptera. Insecticides were applied to each plot two times at 15 day intervals over the course of four weeks. The following formulations were used: Success at 5 fl oz / a; Crymax at 2 lb / a; BetaCide at 10% v / v with Soap at 0.5% v / v; Avaunt at 3.43 oz / a. The soap used was a liquid handsoap (Renown was pink handsoap Deerfield, Ill.). Treatment applications were performed using a CO2 backpack sprayer. The spray boom incorporated six D4 nozzles with #25 spinners and was operated at a pressure of 40-50 psi. Treatments were applied at a dilution of 75 GPA. The boom size was adjusted according to the growth stage of plant to e...
